Dry sump vs
Wet sump |
| In a nutshell, the difference between a wet sump system
and a dry sump system is where the oil is stored. In a wet sump
system the oil is stored in the oil pan itself. The oil is pumped
to your engine using an engine mounted oil pump usually mounted
inside the pan. A dry sump system stores the oil in a remotely
mounted tank. The oil is scavenged or sucked out of the oil pan
and also sometimes from the lifter valley. This oil goes through
a multistage dry sump pump and is then sent to the storage tank.
It is then pulled back through the pump and pumped back into the
engine. Along the way it passes through a series of filters, oil
coolers, yards of stainless braided hose and occasionally has a
short lay over in Pittsburgh waiting for a connecting flight.
(Still awake?) Dry sump systems are more complicated and costly
than wet sumps. Used in higher levels of racing. The average dry
sump set-up has the ability to scavenge 2 to 4 times the volume
that it pumps into the engine. This causes negative crankcase
pressure, which gives you horsepower. Dry sump systems also
offer a more stable supply of oil in all conditions since there
isn’t a rapidly spinning crankshaft located right above the oil.
In a nut shell a dry sump cost more but works better.

Custom Dry Sumps |
| We build several custom dry sump oil pans.
Many are based on our standard designs but are for engine applications
not listed. We don’t stock dry sump pans for foreign engines, domestic
4 and 6 cyl. engines or for less common V-8’s such as AMC’s and Pontiacs
but we build them on a regular basis, and have accumulated considerable
experience in doing so. If you’re looking for a pan that we don’t
stock, feel free to call our Custom Department for a quote and
design recommendations. |
